• Kythnos is an island in the Western Cyclades with a population of 1.632 people and its 5-year

Average Peak Demand is 3,1 MW.

• The island has been a pilot site for many innovative projects which have taken place on the

island during the last three decades:

Innovative Projects in Kythnos (1)

• 1998 - Installation of the new Vestas 500kW wind turbine

• 2000 - Operation of a fully automated power system with 500kW battery storage and a 500kW Wind Turbine

• 2001 - Operation of a Microgrid electrifying 12 houses with intelligent autonomous Load Control

• 1982 - Operation of the first Wind Park in Europe (5x20kW)

• 1983 - Installation of a 100 kW PV system with Battery storage (400kWh)

• 1989 - Replacement of the wind turbines (5x33kW)

• 1992 - Inverters in the PV system

6

• Kythnos Microgrid in Gaidouromantra, consists of 12 houses with PVs and Batteries (52 kWh), 9 kVA

Diesel (only back-up), flexible loads (1-2 kW irrigation pumps) and Intelligent Load Controllers.

Innovative projects in Kythnos (2)

7

• The project combines Hydro Electric power and Wind power and its guaranteed power is 2,55 MW, when the 5-year Average Peak Demand of Ikaria is 7,3 MW.

• The whole project consists of two hydro power plants (1 MW & 3 MW) with two reservoirs that exploit water that comes from a dam and a wind park (2,7 MW) which provides energy to the water pumps (3 MW).

Ikaria’s Hybrid Station

• It is expected that the Hybrid plant will cover 30% of the energy needs of the island.

8

• The project is not yet in operation and it is expected to be partially operated by the end of 2018 with the operation of the wind turbine

• TILOS project is a Horizon 2020 EU funded project located in the island of Tilos.

• Tilos is an island of the Dodecanese complex. It is interconnected with Kos and it is one of the 9 islands of the ES of Kos-Kalymnos, The 5-year Average Peak Demand of the Kos-Kalymnos ES is 94,8 MW.

• The main objective of TILOS project, is the development and operation of a prototype battery system based on NaNiCl2 batteries (2,4MWh) with Wind turbines (800 kW) and PVs (160 kW), provided with an optimum, real-environment smart grid control system and coping with the challenge of supporting multiple tasks including:

• Micro grid energy management

• Maximization of RES penetration

• Grid stability

• Export of guaranteed energy

• Ancillary services to the main grid of Kos

• The project’s guaranteed power is 0,4 MW and it is expected to start its trial operation in autumn of 2018.

TILOS project

• The TILOS project won two European Sustainable Energy Week (EUSEW) Awards in Brussels in 2017. The first ever Energy Islands award and the Citizen’s Award.

• Law 4495/2018 authorizes the Ministry of Energy, RAE and HEDNO to take all necessary actions for the implementation of the project.

Agios Efstratios – “Green Island” project • Agios Efstratios is a small island in the North – East part of

the Aegean Sea, with only 270 inhabitants (2011) and its 5-year Average Peak Demand 0,32 MW.

• The project of Agios Efstratios includes two subprojects, the development of a Hybrid power plant and the development of a District Heating system (teleheating).

• The Hybrid power plant consists of Wind turbines (900 kW), PVs (150 kW) & Batteries (2,5 MWh), which is combined with a District Heating system (Teleheating).

• The target of the project is to accomplish 85% energy of the island to come from RES.

• The project is funded by the EU, it is run by the CRES and it is still under study.

• The target of the “Smart Island” pilot projects is to increase RES penetration, while ensuring the supply of demand and the secure operation of the power systems in a cost efficient way.

• The “Smart Island” pilot projects will be implemented by investors who will have to participate in tenders held by the Regulatory Authority for Energy.

“Smart Island” pilot projects (1)

• During the last 10 years, significant efforts have been made to further enhance RES integration in the Non Interconnected islands.

• Law 4495/2017 & Law 4546/2018 authorize the Ministry of Energy, RAE and HEDNO to take all necessary actions for the implementation of “Smart Island” pilot projects in 3 Greek islands.

• Each pilot project will consist of new RES units in combination with storage units controlled by a smart management system.

11

• In order to promote the implementation of the “Smart Island” pilot projects, according to the Law,

HEDNO was set responsible to issue its suggestion to RAE and the ministry, which has been already

done on the 21st of May 2018, regarding the following subjects:

1. The power systems where the pilot projects are going to be implemented

2. The configuration of the RES and storage units

3. The implementation time

4. The minimum RES penetration margin to be achieved

5. Remuneration issues

6. Special authorization procedures

Public Electric Vehicle Charging Infrastructure (1)

• According to the EU Direction 2014/94/EU, Greece is obliged to have 13,000 electric vehicle charging stations by 2020 (1 charging station per 10 vehicles).

• Today there are less than 45 charging stations in the whole country.

• HEDNO’s Plan for the installation of Electric Vehicle Supply Equipment (EVSE) takes place in order to unlock the market & satisfy the EU Directives.

Phase A Pilot Phase

Installation of Mode 3 (AC 2x22kW)

EV Charging Stations in the Islands

2018-2019 Budget: 450.000 €

Phase B Installation of 1000-1500

Mode 3 (AC 2x22kW) & Mode 4 (DC 50kW)

EV Charging Stations in the Mainland

2019-2020 Budget: ≈ 10M€

15

• The Tender for the purchase of 100 (with an option of -30% ÷ +50%) EV Charging Stations of Phase A is in progress and the opening of the bids is going to take place on the 20th of July 2018

• At least one Charging station is expected to be installed in every island (interconnected and non interconnected) which has an average peak demand higher than 1 MW. Especially for the islands of Crete and Rhodes, 35 and 10 Stations respectively are foreseen.

• HEDNO will be the Charging Points Owner and Operator (CPO). Additionally, HEDNO will be responsible of metering and data management.

• The E-Mobility Service Providers of the charging services, as well as the Energy Suppliers, will be external companies/bodies.
